Modeling the meteorological and chemical effects of secondary organic aerosols during an EUCAARI campaign
A volatility basis set (VBS) approach for the simulation of secondary organic aerosol (SOA) formation is incorporated in the online coupled atmospheric model system COSMO-ART and applied over Europe during the EUCAARI May 2008 campaign. Organic aerosol performance is improved when compared to the default SOA module of COSMO-ART (SORGAM) against high temporal resolution aerosol mass spectrometer...
متن کاملSynergetic formation of secondary inorganic and organic aerosol: effect of SO2 and NH3 on particle formation and growth
The effects of SO2 and NH3 on secondary organic aerosol formation have rarely been investigated together, while the interactive effects between inorganic and organic species under highly complex pollution conditions remain uncertain. Here we studied the effects of SO2 and NH3 on secondary aerosol formation in the photooxidation system of toluene/NOx in the presence or absence of Al2O3 seed aero...
متن کاملContributions of organic and sulfate components to CCN concentrations in a boreal forest
The ability of atmospheric aerosols to nucleate cloud droplets is dependent on both the particle size and composition. Organic compounds significantly contribute to particle composition; thus, their ability to act as cloud condensation nuclei (CCN) is crucial for understanding cloud droplet formation. While the organic fraction can significantly alter the hygroscopicity of particles, the comple...
متن کاملAtmospheric nanoparticles formed from heterogeneous reactions of organics
Atmospheric aerosols directly and indirectly affect the radiative balance of the Earth’s atmosphere1. Nanoparticles are a key component of atmospheric aerosols, growing rapidly under ambient conditions2–4. Organic species are thought to lead to the growth of nanoparticles smaller than 20 nm (refs 5, 6), but the identity of these species and the underlying chemical mechanisms remain elusive. Her...
متن کاملFate of products of degradation processes: consequences for climatic change.
The end products of atmospheric degradation are not only CO2 and H2O but also sulfate and nitrate depending on the chemical composition of the substances which are subject to degradation processes. Atmospheric degradation has thus a direct influence on the radiative balance of the earth not only due to formation of greenhouse gases but also of aerosols. Aerosols of a diameter of 0.1 to 2 microm...
